Abstract
A retrospective pilot study was carried out to investigate the prevalence of four variants of the diamine oxidase (DAO) encoding gene (AOC1) in Caucasian adults with symptoms of histamine intolerance. In a cohort of 100 patients and 100 healthy individuals, DAO-encoding gene non-synonymous Single Nucleotide Variations (SNVs) were genotyped by multiplex single-nucleotide primer extension (SNPE) and capillary electrophoresis, and serum DAO activity was analyzed with a radio-extraction assay. The study found that 79% of individuals with symptoms of histamine intolerance harbored one or more of the four SNVs associated with reduced DAO activity. No significant differences were found in the prevalence of any variant between the group of patients and healthy controls. However, when considering the status of the alleles associated with DAO deficiency, more homozygous alleles were observed in histamine-intolerant patients. Moreover, a slightly but statistically higher percentage of patients had a high genetic risk score, reflecting the cumulative effect of carrying multiple DAO deficiency-associated gene variants and a high load of risk alleles (homozygous). A relationship between serum DAO activity and the genetic load of one specific SNV was observed, with DAO activity being significantly lower in patients homozygous for rs2052129. These results potentially support that carrying multiple DAO deficiency-associated gene variants and a high load of risk alleles (homozygous) is more relevant than the mere presence of one or more SNVs. Further studies are needed to determine the predictive value of these DAO-encoding gene variants.

Abstract
Histamine intolerance (HIT) is assumed to be due to a deficiency of the gastrointestinal (GI) enzyme diamine oxidase (DAO) and, therefore, the food component histamine not being degraded and/or absorbed properly within the GI tract. Involvement of the GI mucosa in various disorders and diseases, several with unknown origin, and the effects of some medications seem to reduce gastrointestinal DAO activity. HIT causes variable, functional, nonspecific, non-allergic GI and extra-intestinal complaints. Usually, evaluation for HIT is not included in differential diagnoses of patients with unexplained, functional GI complaints or in the here-listed disorders and diseases. The clinical diagnosis of HIT is challenging, and the thorough anamnesis of all HIT-linked complaints, using a standardized questionnaire, is the mainstay of HIT diagnosis. So far, DAO values in serum have not been established to correlate with DAO activity in the gut, but the diagnosis of HIT may be supported with determination of a low serum DAO value. A targeted dietary intervention, consisting of a histamine-reduced diet and/or supplementation with oral DAO capsules, is helpful to reduce HIT-related symptoms. This manuscript will present why histamine should also be taken into account in the differential diagnoses of patients with various diseases and disorders of unknown origin, but with association to functional gastrointestinal complaints. In this review, we discuss currently increasing evidence that HIT is primarily a gastrointestinal disorder and that it originates in the gut.

Abstract
Ochratoxin A (OTA) contamination widely occurs in various feed ingredients and food crops, potentially posing a serious health threat to animals. In this research, 1260 juvenile grass carp were separately fed with seven distinct experimental diets (0, 406, 795, 1209, 1612, 2003 and 2406 µg of OTA/kg of diet) for 60 consecutive days to evaluate OTA’s toxic effect on the intestinal apical junctional complex (including the tight junction (TJ) and the adherents junction (AJ)) and the underlying action mechanisms. Our experiment firstly confirmed that OTA caused fish growth retardation and disrupted the intestinal structural integrity. The detailed results show that OTA (1) depressed the feed efficiency, percentage weight gain and specific growth rate; (2) accumulated in the intestine; (3) caused oxidative damage and increased intestinal permeability; and (4) induced the RhoA/ROCK signaling pathway, destroying intestinal apical junctional complexes. Notably, OTA intervention did not result in changes in the gene expression of claudin-3c (in the proximal intestine (PI)), claudin-b and ZO-2b (in the mid intestine (MI) and distal intestine (DI)) in the fish intestine.

Abstract
Single and/or combined food intolerance/malabsorption may cause nonspecific, functional gastrointestinal (GI) complaints. In lactose-intolerant patients we evaluated the influence of additional food intolerance/malabsorption with hydrogen (H2) breath tests. In a retrospective analysis of charts from 279 lactose-intolerant patients, we found 128 patients with only lactose intolerance (LIT). Then, we identified 106 LIT patients with additional histamine intolerance (HIT). Additionally, 45 LIT and HIT patients also had fructose malabsorption (FM). A hydrogen (H2) breath test was performed to evaluate LIT and FM. A serum diamine oxidase value of <10 U/mL and a response to a histamine-reduced diet was used to identify HIT. Using pairwise comparison with the Kruskal-Wallis test to associate the area under the curve (AUC) of LIT patients and, LIT with HIT, to LIT with HIT and FM it was found, that the exhaled hydrogen values were significantly higher in patients with two-fold and triple combined food intolerance/malabsorption (p < 0.004 and p < 0.001, respectively). Within the pool of 170 LIT patients with >20 ppm increase of expiratory H2 from baseline, there were 74 LIT-only patients, 60 LIT with HIT patients, and 36 LIT patients with additional HIT and FM. With the Kruskal-Wallis test AUCs demonstrated a significant difference between all three groups (p = 0.024). In patients with LIT, the presence of additional food intolerance/malabsorption, significantly increases expiratory H2 values. We demonstrate evidence, which may suggest HIT to embody an own GI disorder as food intolerance/malabsorption.

Abstract
Vascular adhesion protein-1 (VAP-1) is a multifunctional protein that plays a role in chronic liver diseases and fibrogenesis. The present study aimed to investigate the possible association of VAP-1 levels with the severity of disease progression in chronic hepatitis (CH) B and C patients with differing stages of fibrosis (F0-4), CHB/CHC-related cirrhosis, and hepatocellular carcinoma (HCC). The VAP-1 concentration in patient sera was determined by ELISA. The VAP-1 levels were compared between the F0 group and the F1, F2, F3, F4, cirrhosis, and HCC groups of CHB patients and between the F1 group and the F2, F3, F4, cirrhosis, and HCC groups of CHC patients. The levels of VAP-1 were significantly increased in CHB patients with progressive stages of fibrosis, with the highest concentration being found in those with stage F4 (severe fibrosis). A statistically significant difference was found between F0 and F4 in patients with CHB, but no statistically significant difference was observed between F1 and F4 in patients with CHC. Interestingly, there was no statistically significant difference in VAP-1 levels between patients with cirrhosis and HCC (either CHB or CHC, independently). Moreover, no relationship was found between VAP-1 and ALT levels in either CHC or CHB patients. In general, the VAP-1 levels were significantly higher in CHB than in CHC patients (P < 0.01). In conclusion, we suggest that the VAP-1 level may be a noninvasive biomarker for monitoring the severity of fibrogenesis in patients with hepatitis B infection.

Abstract
Geriatric frailty is associated with increased mortality and links to increased inflammatory activity. Vascular adhesion protein-1 (VAP-1) is important in inflammatory process. This study investigates the relationship between plasma VAP-1 level and frailty in older adults.The cross-sectional study recruited community dwelling older adults from a hospital-based comprehensive geriatric assessment program. The demographic data, Fried Frailty Index, metabolic and inflammatory parameters were assessed.A total of 151 participants (76 women, 50.3%) were included in the analysis, and the age (mean ± standard deviation) was 77.1 ± 6.1 years. The mean plasma VAP-1 level (ng/mL) was significantly different (P = .029) among different frailty groups (346.3 ± 86.5 in the robust older adults, 371.6 ± 107.9 in the pre-frail older adults, and 416.6 ± 141.1 in the frail older adults). Multivariate ordered logistic regression analysis also demonstrated that plasma VAP-1 levels were positively associated with frailty severity (P = .039). Analysis of the frailty components with plasma VAP-1 levels showed that the elderly who had "exhaustion" (P = .016) or "weakness" (P = .025) tended to have higher plasma VAP-1 levels.The data support that VAP-1 might represent a potential plasma biomarker of frailty.

Abstract
Creatine supplementation of the population with type 2 diabetes mellitus (T2DM) combined with an exercise program is known to be a possible therapy adjuvant with hypoglycemic effects. However, excessive administration of creatine leads to the production of methylamine which is deaminated by the enzyme semicarbazide-sensitive amine oxidase (SSAO) and as a result, cytotoxic compounds are produced. SSAO activity and reaction products are increased in the serum of T2DM patients. Creatine supplementation by diabetics will further augment the activity of SSAO. The current review aims to find a feasible way to ameliorate T2DM for patients who exercise and desire to consume creatine. Several natural agents present in food which are involved in the regulation of SSAO activity directly or indirectly are reviewed. Particularly, zinc-α2-glycoprotein (ZAG), zinc (Zn), copper (Cu), histamine/histidine, caffeine, iron (Fe), and vitamin D are discussed. Inhibiting SSAO activity by natural agents might reduce the potential adverse effects of creatine metabolism in population of T2DM.

Abstract
BACKGROUND More and more studies focus on the relationship between the gastrointestinal microbiome and type 2 diabetes, but few of them have actually explored the relationship between enterotypes and type 2 diabetes. Materials and Methods. We enrolled 134 patients with type 2 diabetes and 37 nondiabetic controls. The anthropometric and clinical indices of each subject were measured. Fecal samples of each subject were also collected and were processed for 16S rDNA sequencing. Multiple logistic regression analysis was used to determine the associations of enterotypes with type 2 diabetes. Multiple linear regression analysis was used to explore the relationship between lipopolysaccharide levels and insulin sensitivity after adjusting for age, BMI, TG, HDL-C, DAO, and TNF-α. The correlation analysis between factors and microbiota was identified using Spearman correlation analysis. The correlation analysis between factors was identified using partial correlation analysis. RESULTS Gut microbiota in type 2 diabetes group exhibited lower bacterial diversity compared with nondiabetic controls. The fecal communities from all subjects clustered into two enterotypes distinguished by the levels of Bacteroides and Prevotella. Logistic regression analysis showed that the Bacteroides and Bacteroides and Prevotella enterotype. Partial correlation analysis showed that lipopolysaccharide was closely associated with diamine oxidase, tumor necrosis factor-alpha, and Gutt insulin sensitivity index after adjusting for multiple covariates. Furthermore, the level of lipopolysaccharide was found to be an independent risk factor for insulin sensitivity. CONCLUSIONS We identified two enterotypes, Bacteroides and Prevotella, among all subjects. Our results showed that the Bacteroides enterotype was an independent risk factor for type 2 diabetes, which was due to increased levels of lipopolysaccharide causing decreased insulin sensitivity.Bacteroides and Prevotella enterotype. Partial correlation analysis showed that lipopolysaccharide was closely associated with diamine oxidase, tumor necrosis factor-alpha, and Gutt insulin sensitivity index after adjusting for multiple covariates. Furthermore, the level of lipopolysaccharide was found to be an independent risk factor for insulin sensitivity. Bacteroides and.

Abstract
BACKGROUND Our previous studies found that intestinal barrier function has been changed in children with abdominal Henoch-Schonlein purpura (HSP). Montmorillonite has been shown to be protective for digestive tract mucosa. OBJECTIVE The present study aimed to investigate whether Montmorillonite powder could improve the intestinal mucosal barrier function in children with abdominal HSP. METHODS Using a randomized controlled study design, we compared plasma levels of diamine oxidase (DAO), D-lactate, and endotoxin in children with abdominal HSP before and after Montmorillonite powder treatment. RESULTS Among 28 patients in experimental group and 30 in control group, there was no significant difference in age, sex, height, weight, and course of disease between 2 groups (P > .05). Before treatment, there was no statistical difference in DAO, D-lactic acid, and endotoxin between experimental group and the control group (P > .05). However, significant differences were detected for DAO and D-lactate after treatment in comparison to before treatment in the Montmorillonite experimental group (P < .05). Such differences were not found in the control group (P > .05). CONCLUSION Montmorillonite powder is effective in the treatment of HSP via maintaining intestinal mucosal barrier function.

Abstract
5-Fluorouracil (5-FU) is the most frequently prescribed anti-tumor drug, but has been reported to result in intestinal injury. Although some progress has been made in understanding the intestinal toxicity of 5-FU, confusion remains about animal models of 5-FU-induced intestinal injury, especially the dosage of 5-FU. This study aims to assess the dose-response relationship between the severity of intestinal injury and different doses of 5-FU, and to determine a proper dosing for the murine model. We found that mice in the 5-FU groups gradually lost body weight over time. Increasing doses of 5-FU resulted in more severe diarrhea, with a concomitant increase in mortality. Histopathological damage was more severe in mice that received higher doses of 5-FU. In addition, plasma diamine oxidase (DAO) activity decreased in experimental mice with intestinal injury in a dose-dependent way. TUNEL and western blot analysis showed cell apoptosis in the ileum and colon related to 5-FU dosage. However, administration of 200 and 400 mg/kg 5-FU caused extremely high mortality, severe diarrhea and histopathological damage, but 25 mg/kg 5-FU did not result in significant intestinal injury. The severity of intestinal injury induced by 5-FU appeared to be dose-dependent and we concluded that the proper dosage of 5-FU to induce a murine model with intestinal mucositis ranged from 50 mg/kg to 100 mg/kg.

Abstract
BACKGROUND Observational studies suggest that higher volumes of physical activity are associated with a lower risk of disease recurrence among survivors of colon cancer. However, the feasibility and safety of prescribing higher volumes of physical activity to survivors of colon cancer are unknown. Furthermore, the pathways through which exercise may reduce disease recurrence are unknown. PATIENTS AND METHODS Survivors of stage I to III colon cancer were randomized to usual-care control, 150 minutes per week of aerobic exercise (low-dose), or 300 minutes per week of aerobic exercise (high-dose). Changes in soluble intercellular adhesion molecule-1 and vascular adhesion molecule-1 prognostic biomarkers were examined. RESULTS From January 2015 to February 2016, 39 patients were enrolled (n = 13 usual-care control; n = 14 low-dose; n = 12 high-dose), and 38 participants completed the study (97% follow-up). Over 6 months, the low-dose group completed 142 minutes per week (92.8% adherence), and the high-dose group completed 247 minutes per week (89.0% adherence) of exercise. Compared with the control group, changes in soluble intercellular adhesion molecule-1 were -134.9 ng/mL (95% confidence interval, -238.1 to -31.6 ng/mL) in the low-dose group and -114.8 ng/mL (95% confidence interval, -222.5 to -7.1 ng/mL) in the high-dose group (linear Ptrend = .023; nonlinear Ptrend = .044). No changes were observed for soluable vascular adhesion molecule-1 (linear Ptrend = .791; nonlinear Ptrend = .604). Non-serious adverse events occurred at similar rates among randomized groups. No serious adverse events occurred. CONCLUSION Higher volumes of moderate-intensity aerobic exercise, up to 300 minutes per week, are feasible, safe, and elicit favorable changes in prognostic biomarkers among patients recently treated for stage I to III colon cancer. These data can be used to guide clinical recommendations for patients, and inform future trials.

Abstract
INTRODUCTION Waist circumference does not distinguish subcutaneous from visceral adipose tissue, which is highly associated with impaired cardiometabolic profile and type-2 diabetes mellitus (T2DM). Because of the complexity of the assessment of visceral fat with imaging techniques, easy-to-apply and low-cost anthropometric measures have been proposed. The aim of the study was to show a possible association between Lipid Accumulation Product Index (LAP Index), Deep-abdominal adiposity tissue Index (DAAT) and Visceral Adiposity Index (VAI) with metabolic profile and adipokines in obese subjects with and without T2DM, and to compare the results with the use of waist circumference isolated. METHODS In this cross-sectional study, we enrolled 101 outpatients with obesity (BMI ≥ 30 kg/m2) of which 48% with diabetes and aged 48.9 ±13.3 years. Demographic, clinical and anthropometric data were collected. Plasma C-reactive protein, interleukin-6, vascular adhesion molecule type 1 and adiponectin levels, lipid profile and fasting glucose were assessed. LAP Index, DAAT and VAI were calculated and body composition was evaluated by bioelectric impedance analyses. Continuous variables were described as mean ±standard deviation, and categorical variables as absolute numbers and percentages. Nonparametric data were log-transformed and Student's t test, Wilcoxon-Mann-Whitney and chi-squared test, Pearson correlation and multiple linear regression were used for statistical analyses. RESULTS In total, 31 men and 70 women were evaluated. Individuals with T2DM showed higher LAP values and percentage of body fat and lower waist circumference and BMI values. DAAT and LAP were positively correlated with BMI, waist circumference, percentage of body fat and free fat mass. After adjustment for age, sex and total body fat, both LAP Index and VAI were associated with plasma adiponectin, LDL-cholesterol, non-HDL cholesterol and VLDL-cholesterol in obese with and without T2DM (all P values ≤ 0.02); fasting glucose remained associated with LAP in obese patients without T2DM (P= 0.01). Waist circumference only correlated with adiponectin in obese subjects without T2DM (P= 0.048). CONCLUSIONS Our data suggest that VAI and LAP Index are good predictors of an impaired cardiometabolic setting in obesity regardless of T2DM status. Besides, we were not able to find associations with waist circumference and biochemical markers in our sample.

Abstract
In this study, the toxic effects of clorpyrifos (CPF) on the gut microbiome and related urine metabolome in mouse (Mus musculus) were investigated. Mice were exposed to a daily dose of 1 mg kg(-1) bodyweight of CPF for 30 d. As a result, CPF significantly altered the gut microbiota composition in terms of the relative abundance of key microbes. Meanwhile, CPF exposure induced the alterations of urine metabolites related to the metabolism of amino acids, energy, short-chain fatty acids (SCFAs), phenyl derivatives and bile acids. High correlations were observed between perturbed gut microbiome and altered metabolic profiles. These perturbations finally resulted in intestinal inflammation and abnormal intestinal permeability, which were also confirm by the histologic changes in colon and remarkable increase of lipopolysaccharide (LPS) and diamine oxidase (DAO) in the serum of CPF-treated mice. Our findings will provide a new perspective to reveal the mechanism of CPF toxicity.

Abstract
BACKGROUND Psoriasis is a chronic relapsing inflammatory skin disease. Vaspin, vascular adhesion protein-1 (VAP-1), chitinase-3-like protein 1 (also known as YKL-40), and high-sensitivity C-reactive protein (hs-CRP) are inflammatory biomarkers. However, with the exception of hs-CRP, the role of these markers in the pathogenesis of psoriasis is yet to be elucidated. This study investigated vaspin, VAP-1, YKL-40, and hs-CRP levels in the serum of psoriatic patients and healthy controls. METHODS A total of 56 patients suffering from psoriasis and 34 age-matched controls were included in the study. Vaspin, VAP-1, YKL-40, and hs-CRP serum levels were evaluated by ELISA. The psoriasis area severity index (PASI) was calculated in all psoriatic patients and patients were divided in two groups according to PASI <10 or ≥10. RESULTS The serum concentration of soluble vaspin was significantly lower in psoriatic patients compared to healthy controls (1.33±0.32 pg/mL, 1.72±0.39 pg/mL, respectively; P<0.001). The serum concentrations of soluble VAP-1 and hs-CRP were significantly higher in psoriatic patients compared to healthy controls (VAP-1: 2.05±0.46 pg/mL, 1.82±0.46 pg/mL, hs-CRP: 4.97±3.53 mg/L, 3.48±0.08 mg/L, respectively; P<0.05). There was no significant difference in the serum concentration of soluble YKL-40 between psoriatic patients and the control group (1.37±0.55 ng/mL, 1.54±0.79 ng/mL, respectively; P>0.05). The mean PASI score was 9.1±8.2 in the patient group. A total of 36 patients had PASI<10 and 20 patients had PASI≥10. The serum concentration of vaspin was the only marker to exhibit a significant difference between the low and high PASI groups (1.40±0.27 pg/mL and 1.20±0.37 pg/mL, respectively; P<0.05). CONCLUSIONS These findings suggest that vaspin and VAP-1 may play a role in the pathogenesis of psoriasis and can be used as markers of the disease. Furthermore, vaspin levels may reflect the severity of disease.

Abstract
BACKGROUND Diabetes is the leading cause of end-stage renal disease (ESRD) worldwide. Vascular adhesion protein-1 (VAP-1) participates in inflammation and catalyzes the deamination of primary amines into aldehydes, hydrogen peroxide, and ammonia, both of which are involved in the pathogenesis of diabetic complications. We have shown that serum VAP-1 is higher in patients with diabetes and in patients with chronic kidney disease (CKD), and can predict cardiovascular mortality in subjects with diabetes. In this study, we investigated if serum VAP-1 can predict ESRD in diabetic subjects. METHODS In this prospective cohort study, a total of 604 type 2 diabetic subjects were enrolled between 1996 to 2003 at National Taiwan University Hospital, Taiwan, and were followed for a median of 12.36 years. The development of ESRD was ascertained by linking our database with the nationally comprehensive Taiwan Society Nephrology registry. Serum VAP-1 concentrations at enrollment were measured by time-resolved immunofluorometric assay. RESULTS Subjects with serum VAP-1 in the highest tertile had the highest incidence of ESRD (p<0.001). Every 1-SD increase in serum VAP-1 was associated with a hazard ratio of 1.55 (95%CI 1.12-2.14, p<0.01) for the risk of ESRD, adjusted for smoking, history of cardiovascular disease, body mass index, hypertension, HbA1c, duration of diabetes, total cholesterol, use of statins, ankle-brachial index, estimated GFR, and proteinuria. We developed a risk score comprising serum VAP-1, HbA1c, estimated GFR, and proteinuria, which could predict ESRD with good performance (area under the ROC curve = 0.9406, 95%CI 0.8871-0.9941, sensitivity = 77.3%, and specificity = 92.8%). We also developed an algorithm based on the stage of CKD and a risk score including serum VAP-1, which can stratify these subjects into 3 categories with an ESRD risk of 0.101%/year, 0.131%/year, and 2.427%/year, respectively. CONCLUSIONS In conclusion, serum VAP-1 can predict ESRD and is a useful biomarker to improve risk stratification in type 2 diabetic subjects.

Abstract
INTRODUCTION Intolerance to various foods, excluding bona fide coeliac disease and lactose intolerance, represents a growing cause of patient visits to allergy clinics.Histamine intolerance is a long-known, multifaceted clinical condition triggered by histamine-rich foods and alcohol and/or by drugs that liberate histamine or block diamine oxidase (DAO), the main enzyme involved in the metabolism of ingested histamine. Histamine limitation diets impose complex, non-standardized restrictions that may severely impact the quality of life of patients. METHODS We retrospectively evaluated 14 patients who visited allergy outpatient facilities in northern Italy with a negative diagnosis for IgE-mediated food hypersensitivity, coeliac disease, conditions related to gastric hypersecretion, and systemic nickel hypersensitivity, and who previously underwent a histamine limitation diet with benefits for their main symptoms. Serum diamine oxidase levels and the clinical response to diamine oxidase supplementation were investigated. RESULTS We found that 10 out of 14 patients had serum DAO activity<10 U/mL, which was the threshold suggested as a cutoff for probable histamine intolerance. Moreover, 13 out of 14 patients subjectively reported a benefit in at least one of the disturbances related to food intolerances following diamine oxidase supplementation. The mean value (±SD) of diamine oxidase activity in the cohort of patients with histamine intolerance symptoms was 7.04±6.90 U/mL compared to 39.50±18.16 U/mL in 34 healthy controls (P=0.0031). CONCLUSION In patients with symptoms triggered by histamine-rich food, measuring the serum diamine oxidase activity can help identify subjects who can benefit from a histamine limitation diet and/or diamine oxidase supplementation.Properly designed, controlled studies investigating histamine intolerance that include histamine provocation are indispensable for providing insights into the area of food intolerances, which are currently primarily managed with non-scientific approaches in Italy.

Abstract
AIM: To investigate whether dimethyl sulfoxide (DMSO) inhibits gut inflammation and barrier dysfunction following zymosan-induced systemic inflammatory response syndrome and multiple organ dysfunction syndrome.
METHODS: Sprague-Dawley rats were randomly divided into four groups: sham with administration of normal saline (SS group); sham with administration of DMSO (SD group); zymosan with administration of normal saline (ZS group); and zymosan with administration of DMSO (ZD group). Each group contained three subgroups according to 4 h, 8 h, and 24 h after surgery. At 4 h, 8 h, and 24 h after intraperitoneal injection of zymosan (750 mg/kg), the levels of intestinal inflammatory cytokines [tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-10] and oxides (myeloperoxidase, malonaldehyde, and superoxide dismutase) were examined. The levels of diamine oxidase (DAO) in plasma and intestinal mucosal blood flow (IMBF) were determined. Intestinal injury was also evaluated using an intestinal histological score and apoptosis of intestinal epithelial cells was determined by deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The intestinal epithelial tight junction protein, ZO-1, was observed by immunofluorescence.
RESULTS: DMSO decreased TNF-α and increased IL-10 levels in the intestine compared with the ZS group at the corresponding time points. The activity of intestinal myeloperoxidase in the ZS group was higher than that in the ZD group 24 h after zymosan administration (P < 0.05). DMSO decreased the content of malondialdehyde (MDA) and increased the activity of superoxide dehydrogenase (SOD) 24 h after zymosan administration. The IMBF was lowest at 24 h and was 49.34% and 58.26% in the ZS group and ZD group, respectively (P < 0.05). DMSO alleviated injury in intestinal villi, and the gut injury score was significantly lower than the ZS group (3.6 ± 0.2 vs 4.2 ± 0.3, P < 0.05). DMSO decreased the level of DAO in plasma compared with the ZS group (65.1 ± 4.7 U/L vs 81.1 ± 5.0 U/L, P < 0.05). DMSO significantly preserved ZO-1 protein expression and localization 24 h after zymosan administration. The TUNEL analysis indicated that the number of apoptotic intestinal cells in the ZS group was much higher than the ZD group (P < 0.05).
CONCLUSION: DMSO inhibited intestinal cytokines and protected against zymosan-induced gut barrier dysfunction.

Abstract
BACKGROUND Chemotherapy-induced mucosal barrier dysfunction is of clinical interest. However, the assessment of mucosal barrier dysfunction still poses challenges. In this study, we compared several biomarkers with the dual sugar gut permeability test for assessing mucosal barrier dysfunction during chemotherapy. METHODS Forty-two patients with gastric or colorectal cancer underwent chemotherapy, including FAM or FOLFOX4 regimens. Patients were asked to grade and record their symptoms of gastrointestinal toxicity daily. The urinary lactulose-mannitol ratio was measured to assess the intestinal permeability. Plasma levels of citrulline, diamine oxidase (DAO), D-lactic acid, and endotoxin were also measured. Intestinal permeability was observed in the subgroup of patients with diarrhea or constipation. RESULTS The urinary lactulose-mannitol ratio and plasma citrulline levels increased on the third and sixth post-chemotherapy days, respectively. There were no significant differences in the plasma levels of D-lactic acid, endotoxin or DAO activity compared to their levels before chemotherapy. The urinary lactulose-mannitol ratio in diarrhea patients was significantly higher than in constipation patients. CONCLUSIONS These results indicate that the urinary lactulose-mannitol ratio and plasma citrulline level are appropriate biomarkers for assessing mucosal barrier dysfunction in patients receiving chemotherapy. Mucosal barrier dysfunction in diarrhea patients was greater than in constipation patients.

Abstract
Background: Intestinal barrier dysfunction would lead to a rigorous inflammatory reaction due to the translocation of intestinal lumen-derived bacteria and endotoxins. The aim of the present study was to investigate whether intestinal barrier dysfunction occurs in patients with acute Stanford type A aortic dissection (ATAAD) and to determine its potential relationship with the plasma levels of several inflammatory biomarkers in the progression of ATAAD. Design and Methods: Serum samples from a total of 46 patients with ATAAD and 36 healthy volunteers were prospectively collected and analyzed. The serum levels of diamine oxidase (DAO), lactate dehydrogenase (LDH), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), and C-reactive protein (CRP) were measured using colorimetric assay, enzyme-linked immunosorbent assay, and immunoturbidimetric assay. Results: Serum levels of DAO, LDH, IL-6, TNF-α, and CRP in patients with ATAAD were significantly higher than those in healthy participants. A significantly positive correlation between DAO activity and IL-6 ( r = .56, P < .001), TNF-α ( r = .63, P < .001), and CRP ( r = .53, P < .001) was observed. Moreover, the activity of DAO correlated negatively with the Pao2/fraction of inspired oxygen (Fio2) ratio ( r = −.39, P = .007). Conclusions: Intestinal barrier dysfunction, reflected by an increased level of serum DAO, may play an important role in the development of systemic inflammatory responses in patients with ATAAD. Therefore, strategies of preserving a normal intestinal barrier function may open new horizons in the treatment of inflammation-related adverse events in the setting of ATAAD.

Abstract
In two patients with carcinoid syndrome, a reduced venoreactivity to serotonin (5-HT) was found by means of the venoconstriction test. Parachlorophenylalanine (PCPA) treatment increased 5-HT venoreactivity. A normal noradrenaline venoreactivity was detected before and during PCPA administration. The altered platelet monoamine oxidase (MAO) activity corrected by PCPA treatment. The abnormal 5-HT turnover may alter the synthesis of MAO and provoke the production of isoenzymes. Low plasma amine oxidase and high plasma histaminase activity were found in 1 of these 2 patients. A low level of plasma prekallikrein in the two patients remained unchanged during PCPA administration.

Abstract
AIM: To investigate the effect of Qingyi decoction on the expression of secreted phospholipase A2 (sPLA2) in intestinal barrier injury.
METHODS: Fifty healthy Sprague-Dawley rats were randomly divided into control, severe acute pancreatitis (SAP), Qingyi decoction-treated (QYT), dexamethasone-treated (DEX), and verapamil-treated (VER) groups. The SAP model was induced by retrograde infusion of 1.5% sodium deoxycholate into the biliopancreatic duct of the rats. All rats were sacrificed 24 h post-SAP induction. Arterial blood, intestine, and pancreas from each rat were harvested for investigations. The levels of serum amylase (AMY) and diamine oxidase (DAO) were determined using biochemical methods, and serum tumor necrosis factor (TNF)-α level was measured by an enzyme linked immunosorbent assay. Pathologic changes in the harvested tissues were investigated by microscopic examination of hematoxylin and eosin-stained tissue sections. The expressions of sPLA2 at mRNA and protein levels were detected by reverse transcriptase PCR and Western blot, respectively. A terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay was used to investigate apoptosis of epithelial cells in the intestinal tissues.
RESULTS: Compared to the control group, the expression of sPLA2 at both the mRNA and protein levels increased significantly in the SAP group (0.36 ± 0.13 vs 0.90 ± 0.38, and 0.16 ± 0.05 vs 0.64 ± 0.05, respectively; Ps < 0.01). The levels of AMY, TNF-α and DAO in serum were also significantly increased (917 ± 62 U/L vs 6870 ± 810 U/L, 59.7 ± 14.3 ng/L vs 180.5 ± 20.1 ng/L, and 10.37 ± 2.44 U/L vs 37.89 ± 5.86 U/L, respectively; Ps < 0.01). The apoptosis index of intestinal epithelial cells also differed significantly between the SAP and control rats (0.05 ± 0.02 vs 0.26 ± 0.06; P < 0.01). The serum levels of DAO and TNF-α, and the intestinal apoptosis index significantly correlated with sPLA2 expression in the intestine (r = 0.895, 0.893 and 0.926, respectively; Ps < 0.05). The levels of sPLA2, AMY, TNF-α, and DAO in the QYT, VER, and DEX groups were all decreased compared with the SAP group, but not the control group. Qingyi decoction intervention, however, gave the most therapeutic effect against intestinal barrier damage, although the onset of its therapeutic effect was slower.
CONCLUSION: Qingyi decoction ameliorates acute pancreatitis-induced intestinal barrier injury by inhibiting the overexpression of intestinal sPLA2. This mechanism may be similar to that of verapamil.

Abstract
BACKGROUND Recent studies have suggested that pyruvate-enriched oral rehydration solution (Pyr-ORS) may be superior to the standard bicarbonate-based ORS in the protection of intestine from ischemic injury. The aim of this study was to compare the effects of Pyr-ORS with citrate-enriched ORS (Cit-ORS) on the intestinal hypoxia-inducible factor-1 (HIF-1)-erythropoietin (EPO) signaling pathway for enteral rehydration in a rat model of burn injury. METHODS Rats were randomly assigned to 4 groups (N = 20, 2 subgroups each: n = 10): scald sham (group SS), scald with no fluid resuscitation (group SN), scald and resuscitation with enteral Cit-ORS (group SC), and scald and resuscitation with enteral Pyr-ORS (group SP). At 2.5 and 4.5 hours after a 35% total body surface area (TBSA) scald, intestinal mucosal blood flow (IMBF), contents of HIF-1, EPO, endothelial nitric oxide synthase (eNOS), nitric oxide (NO), barrier protein (ZO-1), levels of serum diamine oxidase (DAO), and intestinal mucosal histology injury score were determined. RESULTS Serum DAO activities in the scalded groups were significantly elevated, but less raised in group SP than in group SC, at 2.5 hours and at 4.5 hours after the scald. Further, group SP more profoundly preserved intestinal HIF-1 expression compared with group SC at the 2 time points. Compared with group SC, group SP had markedly elevated intestinal EPO, eNOS, and NO levels at the same time points, respectively (P < .05). Similarly, IMBF and ZO-1 levels were significantly higher in group SP than in group SC. Intestinal mucosal histopathological scores were statistically higher at 2.5 hours and 4.5 hours after scalding but were more attenuated in group SP than in group SC (P < .05). Immunofluorescence expression of intestinal mucosal ZO-1 was consistent with the above changes. The above parameters were also significantly different between groups SC and SN (all P < .05). CONCLUSION Pyr-ORS provides a superior option to Cit-ORS for the preservation of intestinal blood flow and barrier function and the attenuation of histopathological alterations in enteral resuscitation of rats with burn injury. Its underlying mechanism may be closely related to the pyruvate in activation of intestinal HIF-1-EPO signaling cascades.

Abstract
OBJECTIVE To explore the effects of oral administration of mixed enteral nutritional agent on intestinal mucosal barrier of patients with severe burn injury at early stage. METHODS Twenty-four patients with severe burn injury admitted to our burn ward from August 2013 to September 2014, conforming to the study criteria, were divided into conventional therapy group (n = 12) and early enteral feeding group (n = 12) according to the random number table. Patients in conventional therapy group received conventional treatment immediately after admission, while those in early enteral feeding group were orally given 100 mL of a mixture of glutamine, probiotics, and prebiotics once a day besides conventional treatment for 7 days. Serum levels of diamine oxidase (DAO) and procalcitonin (PCT) and plasma level of LPS were determined by ELISA before treatment and on treatment day (TD) 1, 3, 7, 14, and 21. Wound secretion and blood samples were collected for bacterial culture within the 21 TD. The incidence of MODS within the 21 TD was observed. Data were processed with Fisher's exact test, rank sum test, analysis of variance for repeated measurement, and LSD-t test. RESULTS (1) Serum levels of DAO in patients of early enteral feeding group on TD 7, 14, and 21 were respectively (14.9 ± 3.7), (12.4 ± 3.1), and (9.5 ± 0.7) ng/mL, which were significantly lower than those of conventional therapy group [(17.5 ± 4.0), (16.3 ± 3.3), and (13.0 ± 1.1) ng/mL, with t values from 2.913 to 15.304, P values below 0.01]. Serum levels of DAO at the other time points were close between the two groups (with t values from -0.598 to 0.139, P values above 0.05). (2) Compared with serum levels of PCT in patients of conventional therapy group [(11.7 ± 20.9) and (12.9 ± 23.9) ng/mL], those of early enteral feeding group were significantly lower on TD 7 and 14 [(2.7 ± 8.1) and (2.0 ± 5.6) ng/mL, with Z values respectively -2.919 and -2.139, P < 0.05 or P < 0.01]. Serum levels of PCT at the other time points were close between the two groups (with Z values from -1.833 to -0.346, P values above 0.05). (3) Plasma level of LPS in patients of early enteral feeding group on TD 7 was (33 ± 56) pg/mL, which was significantly lower than that of conventional therapy group [(102 ± 108) pg/mL, Z = -2.046, P < 0.05]. Plasma levels of LPS at the other time points between the two groups showed no significant difference (with Z values from -2.003~-0.526, P values above 0.05). (4) Positive results in bacterial culture of wound secretion were approximately the same between the two groups (P > 0.05). Bacterial culture of blood was positive in 7 patients of conventional therapy group and 1 patient of early enteral feeding group, showing significantly statistical difference (P < 0.05). MODS was observed in 1 patient of conventional therapy group, showing no significantly statistical difference with that of early enteral feeding group (no patient, P > 0.05). CONCLUSIONS Early intestinal feeding of mixed enteral nutritional agent in addition to conventional therapy can effectively promote repair of the impairment of intestinal mucosal barrier, protect integrity of intestinal mucosa, reduce damage to intestines, and alleviate inflammatory response in patients suffering from severe burn injury.

Abstract
Nonalcoholic fatty liver disease (NAFLD) encompasses a range of manifestations, including steatosis and cirrhosis. Progressive disease is characterized by hepatic leukocyte accumulation in the form of steatohepatitis. The adhesion molecule vascular adhesion protein-1 (VAP-1) is a membrane-bound amine oxidase that promotes leukocyte recruitment to the liver, and the soluble form (sVAP-1) accounts for most circulating monoamine oxidase activity, has insulin-like effects, and can initiate oxidative stress. Here, we determined that hepatic VAP-1 expression is increased in patients with chronic liver disease and that serum sVAP-1 levels are elevated in patients with NAFLD compared with those in control individuals. In 4 murine hepatic injury models, an absence or blockade of functional VAP-1 reduced inflammatory cell recruitment to the liver and attenuated fibrosis. Moreover, disease was reduced in animals expressing a catalytically inactive form of VAP-1, implicating enzyme activity in the disease pathogenesis. Within the liver, hepatic stromal cells expressed functional VAP-1, and evaluation of cultured cells revealed that sVAP-1 promotes leukocyte migration through catalytic generation of ROS, which depended on VAP-1 enzyme activity. VAP-1 enhanced stromal cell spreading and wound closure and modulated expression of profibrotic genes. Together, these results link the amine oxidase activity of VAP-1 with hepatic inflammation and fibrosis and suggest that targeting VAP-1 has therapeutic potential for NAFLD and other chronic fibrotic liver diseases.

Abstract
Background In prolonged hemorrhagic shock, reductions in intestinal mucosal blood perfusion lead to mucosal barrier damage and systemic inflammation. Gastrointestinal failure in critically ill patients has a poor prognosis, so early assessment of mucosal barrier injury in shock patients is clinically relevant. Unfortunately, there is no serum marker that can accurately assess intestinal ischemia-reperfusion injury. Objective The aim of this study was to assess if serum diamine oxidase levels can reflect intestinal mucosal injury subsequent to prolonged hemorrhagic shock. Methods Thirty New Zealand white rabbits were divided into three groups: a control group, a medium blood pressure (BP) group (exsanguinated to a shock BP of 50 to 41 mm Hg), and a low BP group (exsanguinated to a shock blood pressure of 40 to 31 mm Hg), in which the shock BP was sustained for 180 min prior to fluid resuscitation. Results The severity of hemorrhagic shock in the low BP group was significantly greater than that of the medium BP group according to the post-resuscitation BP, serum tumor necrosis factor (TNF)-α, and arterial lactate. Intestinal damage was significantly more severe in the low BP group according to Chiu’s scoring, claudin-1, intercellular adhesion molecule (ICAM)-1, and myeloperoxidase expression. Serum diamine oxidase was significantly increased in the low BP group compared to the medium BP and control groups and was negatively correlated with shock BP. Conclusion Serum diamine oxidase can be used as a serological marker in evaluating intestinal injury and shows promise as an indicator of hemorrhagic shock severity.

Abstract
The mycotoxin deoxynivalenol (DON), one of the most common food contaminants, primarily targets the gastrointestinal tract to affect animal and human health. This study was conducted to examine the protective function of glutamic acid on intestinal injury and oxidative stress caused by DON in piglets. Twenty-eight piglets were assigned randomly into 4 dietary treatments (7 pigs/treatment): 1) uncontaminated control diet (NC), 2) NC+DON at 4 mg/kg (DON), 3) NC+2% glutamic acid (GLU), and 4) NC+2% glutamic acid + DON at 4 mg/kg (DG). At day 15, 30 and 37, blood samples were collected to determine serum concentrations of CAT (catalase), T-AOC (total antioxidant capacity), H2O2 (hydrogen peroxide), NO (nitric oxide), MDA (maleic dialdehyde), DAO (diamine oxidase) and D-lactate. Intestinal morphology, and the activation of Akt/mTOR/4EBP1 signal pathway, as well as the concentrations of H2O2, MDA, and DAO in kidney, liver and small intestine, were analyzed at day 37. Results showed that DON significantly (P<0.05) induced oxidative stress in piglets, while this stress was remarkably reduced with glutamic acid supplementation according to the change of oxidative parameters in blood and tissues. Meanwhile, DON caused obvious intestinal injury from microscopic observations and permeability indicators, which was alleviated by glutamic acid supplementation. Moreover, the inhibition of DON on Akt/mTOR/4EBP1 signal pathway was reduced by glutamic acid supplementation. Collectively, these data suggest that glutamic acid may be a useful nutritional regulator for DON-induced damage manifested as oxidative stress, intestinal injury and signaling inhibition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lycium barbarum and Astragalus membranaceus are two traditional medicinal herbs widely used in China for nourishing Yin and reinforcing Qi. The purpose of the study was to investigate the prophylactic and curative effects of crude polysaccharides (QHPS) extracted from a two-herb formula composed of Lycium barbarum and Astragalus membranaceus at a ratio of 2:3 in colitis rats, and to further elucidate the potential mechanism of action in epithelial cell proliferation in vitro. MATERIALS AND METHODS An acetic acid (AA)-induced ulcerative colitis rat model was applied in the study. Two independent protocols were used to assess the prophylactic and curative effects of QHPS, respectively, in which rats were either pre-treated with QHPS (0.18g/kg) for 14 days prior to AA induction, or post-treated with QHPS for 7 days after AA induction. The stool consistency and weight loss were used to evaluate disease activity. The morphological changes in intestinal mucosa at the end of the experiments were observed. The serum levels of endotoxin (EDT), diamine oxidase (DAO) and d-lactate (DLA), important biochemical markers for evaluating intestinal mucosal structure and function, were measured. In the in vitro mechanistic studies, rat intestinal epithelial cells (IEC-6) were used to access for epithelium regeneration. RESULTS The intra-colonic instillation of AA induced ulcerative colitis in rat, as indicated by diarrhea, weight loss, and colonic mucosal damage. Both prophylactic and curative treatments effectively reduced the weight loss and diarrhea and attenuated the colonic mucosal damage associated with inducible colitis. The significant increase in serum levels of DAO, DLA and EDT was induced by AA and inhibited by QHPS treatment. Moreover, QHPS could significantly stimulate IEC-6 proliferation in a dose-dependent manner (p<0.05). CONCLUSION The present study indicated for the first time that polysaccharides extracted from this two-herb formula can protect against experimental ulcerative colitis, presumably by promoting the recovery of the intestinal barrier.

Abstract
AIM This study aims to investigate and evaluate the efficacy and safety of early enteral nutrition (EN) in maintaining and improving the postoperative nutritional status in patients undergoing esophagectomy. METHODS A randomized, controlled clinical trial was conducted in 120 adult patients with esophageal cancer and undergoing esophagectomy. Patients were randomly divided into two groups receiving either EN (N.=64) or parenteral nutrition (PN) (N.=56) postoperatively. The nutritional intake was isonitrogenic and isocalorie for both groups. Nutritional status was evaluated preoperatively as well as on postoperative day I and day 8. Daily nitrogen balance was measured and 7-day cumulative nitrogen balance was calculated. The levels of serum markers including d-lactate, diamine oxidase (DAO), and endotoxin were determined on 1st, 4th and 8th postoperative day for analyzing intestinal barrier function. Postoperative infection rate and the incidence of nutrition support-related complications were examined. RESULTS The concentrations of serum albumin and prealbumin in patients of EN group were significantly higher than those in PN group and the concentrations of blood glucose, γ-GT, AKP, TB, and DB were significantly lower compared to those in the PN group (P<0.05). Both daily nitrogen balance and cumulative nitrogen balance of EN group were better than those of PN group since postoperative day III. The serum levels of d-lactate, DAO, and endotoxin of EN group were significantly lower than those of PN group on postoperative day VIII (P<0.01). The incidence of postoperative infections in blood, lung, and intestinal tract in EN group was lower compared to PN group (P<0.05). No severe complications associated with nutritional support occurred in EN group. The time to flatus passage in EN group was significantly shorter, and the cost of nutritional support was significantly less compared to PN group (P<0.05). CONCLUSION Postoperative early enteral nutrition was safe and feasible for patients undergoing esophagectomy. Compared to PN, EN more efficiently ameliorated postoperational nutritional status of the patients undergoing esophagectomy, played an important role in restoring intestinal barrier function postoperatively, reduced the incidence of postoperative infection, and decreased the cost of hospital stay.

Abstract
BACKGROUND VAP-1 (vascular adhesion protein-1) is a copper-containing SSAO (semicarbazide-sensitive amine oxidase) secreted by vascular smooth muscle cells, adipocytes, and endothelial cells. Elevation of SSAO activity is observed in atherosclerosis, diabetes mellitus, and obesity. The aim of the study was to assess VAP-1 in prevalent heart and kidney allograft recipients. METHODS Complete blood count, urea, serum lipids, fasting glucose, and creatinine were studied by standard laboratory methods. VAP-1, N-terminal pro brain natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hsCRP) were estimated using commercially available assays. RESULTS Healthy volunteers showed higher hemoglobin and estimated glomerular filtration rate (eGFR) but lower creatinine, NT-proBNP, hsCRP and VAP-1 relative to heart and kidney transplantation (OHT) (KTx). Among heart transplant recipients, VAP-1 correlated with age, presence of diabetes, insulin therapy, ejection fraction, estimated glomerular filtration rate by MDRD (Modification of Diet in Renal Disease), eGFR by CKD-EPI (Chronic Kidney Disease-Epidemiological Collaboration), use of tacrolimus, LVIDd (left ventricular internal end-diastolic dimension), New York Heart Association class and NT-proBNP. VAP-1 was significantly lower among patients treated with tacrolimus than cyclosporine. Diabetic patients versus nondiabetic subjects as well as patients with eGFR below 60 versus ≥ 60 mL/min showed higher serum VAP-1 in OHT and KTx populations. Multiple regression analysis revealed VAP-1 to be predicted in 25% by LVIDd, and use of tacrolimus in OHT. In kidney transplant recipients, VAP-1 correlated only with time after transplantation and serum glucose. CONCLUDING: VAP-1 elevations in heart transplant recipients were predominantly dependent on left ventricular diameter and use of tacrolimus; however, the precise associations with the immunosuppressive regimen warrant further studies. VAP-1 elevations in kidney transplant recipients may relate to glucose control.

Abstract
AIM: To investigate whether miRNA-155 (miR-155) dysregulates apical junctional complex (AJC) protein expression in experimental severe acute pancreatitis (SAP).
METHODS: Twenty-four male BALB/c mice were randomly assigned to two groups: the SAP group (n = 12) receiving sequential intraperitoneal injection of 50 µg/kg caerulein and 10 mg/kg lipopolysaccharide over 6 h, and the control group (n = 12) receiving intraperitoneal injection of normal saline. Animals were sacrificed 3 h following the last injection for collection of blood samples and pancreas and distal ileal segment specimens. Routine pancreas and intestine histology was used to assess SAP pathology and intestinal epithelial barrier damage. Levels of serum amylase, diamine oxidase (DAO), and tumor necrosis factor (TNF)-α were determined using commercial kits. Total RNA samples were isolated from intestinal epithelial specimens and reversely transcribed into cDNA. miR-155 and RhoA mRNA expression profiles were determined using quantitative real-time polymerase chain reaction. Target genes for miR-155 were predicted using the miRTarBase database, RNA22 and PicTar computational methods. Western blotting was performed to quantitate the protein expression levels of the target gene RhoA, as well as zonula occludens (ZO)-1 and E-cadherin, two AJC component proteins.
RESULTS: Intraperitoneal injection of caerulein and lipopolysaccharide successfully induced experimental acute pancreatic damage (SAP vs control, 10.0 ± 2.0 vs 3.2 ± 1.2, P < 0.01) and intestinal epithelial barrier damage (3.2 ± 0.7 vs 1.4 ± 0.7, P < 0.01). Levels of serum amylase (21.6 ± 5.1 U/mL vs 14.3 ± 4.2 U/mL, P < 0.01), DAO (21.4 ± 4.1 mg/mL vs 2.6 ± 0.8 mg/mL, P < 0.01), and TNF-α (61.0 ± 15.1 ng/mL vs 42.9 ± 13.9 ng/mL, P < 0.01) increased significantly in SAP mice compared to those in control mice. miR-155 was significantly overexpressed in SAP intestinal epithelia (1.94 ± 0.50 fold vs 1.03 ± 0.23 fold, P < 0.01), and RhoA gene containing three miR-155-specific binding sites in the three prime untranslated regions was one of the target genes for miR-155. RhoA (22.7 ± 5.8 folds vs 59.6 ± 11.6 folds, P < 0.01), ZO-1 (46 ± 18 folds vs 68 ± 19 folds, P < 0.01), and E-cadherin proteins (48 ± 15 folds vs 77 ± 18 folds, P < 0.01) were underexpressed in SAP intestinal epithelia although RhoA mRNA expression was not significantly changed in SAP (0.97 ± 0.18 folds vs 1.01 ± 0.17 folds, P > 0.05).
CONCLUSION: TNF-α-regulated miR-155 overexpression inhibits AJC component protein syntheses of ZO-1, and E-cadherin by downregulating post-transcriptional RhoA expression, and disrupts intestinal epithelial barrier in experimental SAP.

Abstract
Ginsenoside Rb1 (RB1), the most clinically effective constituent of ginseng, possesses a variety of biological activities. The objectives of this study were to investigate the protective effects of RB1 and its underlying mechanism on renal injury induced by intestinal ischemia-reperfusion (IIR) in mice. RB1 was administered prior to inducing IIR achieved by occluding the superior mesenteric artery for 45 min followed by 120 min of reperfusion. All-trans-retinoic acid (ATRA) was used as an inhibitor of NF-E2-related factor-2 (Nrf2) signaling. Adult male C57BL/6J mice were randomly divided into six groups: (1) sham group, (2) IIR group, (3) RB1 group, (4) sham + ATRA group, (5) IIR + ATRA group, and (6) RB1 + ATRA group. Intestinal histology and pathological injury score were observed. Intestinal mucosal injury was also evaluated by measuring serum diamine oxidase (DAO). Renal injury induced by IIR was characterized by increased levels of histological severity score, blood urea nitrogen (BUN), serum creatinine (Scr) and neutrophil gelatinase-associated lipocalin (NGAL), which was accompanied with elevated renal TUNEL-positive cells and the Bcl-2/Bax expression ratio. RB1 significantly reduced renal injury and apoptosis as compared with IIR group, which was reversed by ATRA treatment. Immunohistochemistry and Western blot analysis demonstrated that RB1 significantly upregulated the protein expression of heme oxygenase-1 (HO-1) and Nrf2, which were attenuated by ATRA treatment. Taken together, these results suggest that the protective effects of RB1 pretreatment against renal injury induced by IIR are associated with activation of the Nrf2/ anti-oxidant response element (ARE) pathway.

Abstract
OBJECTIVES To monitor intra-abdominal pressure (IAP) and intestinal barrier function in a rat model of acute necrotizing pancreatitis (ANP) to elucidate a potential relevant therapeutic window. METHODS Sprague-Dawley rats were randomly divided into experimental or control groups. The ANP group (n = 40) was injected with 4.5% sodium taurocholate into the pancreatic duct to induce ANP. The controls received only abdominal opening surgery (sham-operated, SO; n = 40) or no treatment or surgery (baseline; 0 h, n = 20). The SO and ANP groups were then randomly subdivided into 3, 6, 12 and 24 h groups (n = 10 each). IAP was measured at each time point and the rats were sacrificed to measure the weight of accumulated ascites fluid and the amylase, endogenous creatinine (Cr), total bilirubin (TB), tumor necrosis factor- alpha (TNF-alpha), diamine oxidase (DAO), and D-lactate. Mortality and the development of pathological changes in the pancreas and intestines were also monitored. RESULTS IAP showed a continuous upward trend in the ANP group, with values 2 to 3 times higher than those in the SO group at the corresponding time points and the rising rate was peaking at 6 h. The levels of plasma amylase, TNF-alpha, Cr, TB, DAO, and D-lactate also gradually increased in the ANP group over time and were significantly higher than in the SO group at 3, 6, 12 and 24 h (all P<0.05). Moreover, the rising rate of TNF-alpha, DAO, and D-lactate also peaked at 6 h. CONCLUSIONS The ANP-induced changes in IAP, inflammatory factors and intestinal barrier that we observed in the rat model were especially obvious at 6 h post-induction, suggesting an early therapeutic window for the treatment of ANP in humans.

Abstract
AIM: To investigate the effect of bone-marrow mesenchymal stem cells (BM MSCs) on the intestinal mucosa barrier in ischemia/reperfusion (I/R) injury.
METHODS: BM MSCs were isolated from male Sprague-Dawley rats by density gradient centrifugation, cultured, and analyzed by flow cytometry. I/R injury was induced by occlusion of the superior mesenteric artery for 30 min. Rats were treated with saline, BM MSCs (via intramucosal injection) or tumor necrosis factor (TNF)-α blocking antibodies (via the tail vein). I/R injury was assessed using transmission electron microscopy, hematoxylin and eosin (HE) staining, immunohistochemistry, western blotting and enzyme linked immunosorbent assay.
RESULTS: Intestinal permeability increased, tight junctions (TJs) were disrupted, and zona occludens 1 (ZO-1) was downregulated after I/R injury. BM MSCs reduced intestinal mucosal barrier destruction, ZO-1 downregulation, and TJ disruption. The morphological abnormalities after intestinal I/R injury positively correlated with serum TNF-α levels. Administration of anti-TNF-α IgG or anti-TNF-α receptor 1 antibodies attenuated the intestinal ultrastructural changes, ZO-1 downregulation, and TJ disruption.
CONCLUSION: Altered serum TNF-α levels play an important role in the ability of BM MSCs to protect against intestinal I/R injury.

Abstract
INTRODUCTION There is no valid and reliable diagnostic test for early diagnosis of acute mesenteric ischemia (AMI). The aim of this study was to measure the plasma levels of diamine oxidase (DAO) and citrulline in AMI to gain insight into its early diagnosis. MATERIAL AND METHODS A total of 21 Wistar albino rats were divided into three groups, that is, control group, short-term ischemia group, and prolonged ischemia group. The superior mesenteric artery was occluded for 15 min in the short-term ischemia group and for 12 h in the prolonged ischemia group. Twelve hours later, the experiment was terminated and plasma DAO and citrulline levels were measured. Intestinal tissue was evaluated for the histopathological changes. RESULTS Compared to the control group, the short-term and prolonged ischemia groups showed significant increases in the plasma levels of DAO, whereas the plasma citrulline levels decreased significantly. Prolonged ischemia caused a larger increase in the plasma DAO levels and a larger decrease in the plasma citrulline levels compared to the short-term ischemia (p=0.011 and p=0.021, respectively). Intestinal damage was shown to develop more in the prolonged ischemia group (p=0.001). CONCLUSION In the early period of AMI, the plasma DAO levels increase while citrulline levels decrease, and the extent of these changes depends on the duration of ischemia.

Abstract
AIMS To study serum levels of soluble vascular adhesion protein (sVAP)-1 in type II diabetic patients with retinopathy. METHODS Serum samples were obtained from 53 consecutive patients, including 14 cases with non-angiogenic ocular diseases, i.e., epiretinal membrane (ERM) and idiopathic macular hole (MH), 19 cases with age-related macular degeneration (AMD), and 20 cases with diabetic retinopathy (DR). Protein levels of sVAP-1, intercellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1, and vascular endothelial growth factor (VEGF) were determined by enzyme-linked immunosorbent assay. Enzymatic activity of semicarbazide-sensitive amine oxidase (SSAO) was also measured. RESULTS Serum level of sVAP-1 showed a moderate correlation with SSAO activity in all cases. Patients with DR had higher levels of serum sVAP-1 than subjects with ERM and MH, or those with AMD; however, severity of DR is not related to the serum levels of sVAP-1. Serum sVAP-1 correlated positively with VEGF in patients with DR, but not in those with ERM and MH, or those with AMD. Neither soluble ICAM-1 nor VCAM-1 correlated with VEGF, even in subjects with DR. CONCLUSION The current data demonstrate the elevated serum levels of sVAP-1 and correlation between sVAP-1 and VEGF in patients with type II diabetes.

Abstract
Johne's disease (JD) is a widespread and economically important chronic inflammatory disease of the small intestine of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). Although there are several techniques available for diagnosis of JD, their sensitivity is questionable. New proteome profiling methods, such as serum/plasma protein fingerprinting by 2-Dimensional Fluorescence Difference Gel Electrophoresis (2D-DIGE), may therefore be useful for identifying novel protein biomarkers of MAP infection. In this study, plasma samples were collected from 380 Holstein cows and screened for the presence of MAP infection using the M.pt. Johne's antibody Kit (IDEXX). Five negative (MAP-), and 5 strongly positive (MAP+) cows were selected for proteomic analysis. Highly abundant proteins were depleted from the plasma samples using the ProteoMiner technology (Bio-Rad) to enhance the resolution of low abundance proteins. Plasma samples from MAP-, MAP+, and a pooled internal control were labelled with different fluorescent dyes and separated based on their isoelectrical point (IP) and then their molecular weight. Gel images of the fluorescent plasma protein maps were acquired using a Typhoon scanner and analyzed using the DeCyder software. Proteins that were differentially expressed were excised from the gels, trypsin digested, and subjected to MS/MS analysis for identification. Six proteins were identified as being up-regulated at least 2-fold in MAP+ cows including: transferrin, gelsolin isoforms α & β (actin binding protein - ABP), complement subcomponent C1r, complement component C3, amine oxidase - copper containing 3 (AOC3), and coagulation factor II (thrombin) (p<0.05). Two proteins that were down-regulated approximately 2-fold in the MAP+ cows included coagulation factor XIII -B polypeptide (COAFXIII), and fibrinogen γ chain (FGG) and its precursor.

Abstract
BACKGROUND/AIMS We investigated changes in serum diamine oxidase (DAO) activity during superior mesenteric arterial occlusion. We aimed to evaluate its value in the early diagnosis of superior mesenteric arterial occlusion. METHODOLOGY Seventy mature male Sprague-Dawley rats were used in the study. These were divided into 7 groups of 10 rats each: 10min, 15min, 30min, 45min, 60min and 90min superior mesenteric arterial occlusion (SMA-O) groups, and a sham group. Blood samples were taken at the indicated time points for measuring serum DAO activity. Simultaneously, the small-intestinal segments were assessed histologically and graded according to Chiu's score. RESULTS In the 15min group, SMA-O resulted in a rapid increase in DAO activity. Serum DAO activity and the mucosal injury score fitted well with the cubic model (r2=0.985, p<0.01). There was a positive correlation between ischemic duration and small-intestinal mucosal injury (r=0.909, p<0.01). Taking DAO=29.81U/L as a early diagnostic standard for superior mesenteric arterial occlusion, the sensitivity, accuracy and specificity were 94.34% (50/53), 95.71% (67/70), 100% (17/17), respectively. CONCLUSIONS Serum DAO activity is a sensitive predictor of small-intestinal injury. Our finding suggests that measurement of serum DAO levels might provide a marker for early diagnosis of superior mesenteric arterial occlusion.

Abstract
BACKGROUND This study done was to investigate the clinical significance of soluble vascular adhesion protein-1 (sVAP-1) activity in trauma patients with different patterns. METHODS 96 patients with consecutive trauma ≥15 years who were admitted to emergency department of the Second Affiliated Hospital, Shantou University Medical College, China, between January 2007 and December 2009 were enrolled in this study. Plasma was collected at admission. Injury-severity score (ISS) and Glasgow Coma Scale (GCS) were used to determine the patient conditions. sVAP-1 activity was determined by using the high performance liquid chromatographic (HPLC) system. RESULTS Mean sVAP-1 activity in trauma patients was significantly lower than that of controls (P<0.0001), and the level was negatively correlated with circulating leucocytes and neutrophils (P<0.0001). There was a significant correlation between lower sVAP-1 activity and injury patterns. However, plasma sVAP-1 activity increased significantly in accordance with the severity of traumatic brain injury (TBI), and the patients with sVAP-1 value above 8.61 nmol/ml/h have much higher mortality rate (25.0%) than patients with sVAP-1 value lower than 8.61 nmol/ml/h (0.0%) (P=0.011). CONCLUSIONS Trauma patients had a decreased sVAP-1 activity. However, isolated TBI patients with higher activity of sVAP-1 at admission were more likely to have a poor outcome.

Abstract
BACKGROUND Histamine intolerance (HIT) is associated with an excess of histamine because of an impaired function of the histamine-degrading enzyme diamine oxidase (DAO). The genetic background of HIT is unknown yet. METHODS Case-control association study of all haplotype tagging and four previously reported DAO SNPs and one HNMT Single nucleotide polymorphism with symptoms of HIT and DAO serum activity in 484 German individuals including 285 patients with clinical symptoms of HIT and 199 controls. RESULTS Diamine oxidase serum activity was significantly associated with seven SNPs within the DAO gene. The minor allele at rs2052129, rs2268999, rs10156191 and rs1049742 increased the risk for a reduced DAO activity whereas showing a moderate protective effect at rs2071514, rs1049748 and rs2071517 in the genotypic (P = 2.1 × 10(-8) , 7.6 × 10(-10) , 8.3 × 10(-10) , 0.009, 0.005, 0.00001, 0.006, respectively) and allelic genetic model (P = 2.5 × 10(-11) , 5.4 × 10(-13) , 8.9 × 10(-13) , 0.00002, 0.006, 0.0003, 0.005, respectively). Reporter gene assays at rs2052129 revealed a lower promoter activity (P = 0.016) of the minor allele. DAO mRNA expression in peripheral blood mononuclear cells of homozygous carriers of the minor allele at rs2052129, rs2268999, rs10156191 was lower (P = 0.002) than homozygous carriers of the major allele. Diamine oxidase variants were not associated with the HIT phenotype per se, only with DAO activity alone and the subgroup of HIT patients displaying a reduced DAO activity. CONCLUSIONS DAO gene variants strongly influence DAO expression and activity but alone are not sufficient to fully effectuate the potentially associated disease state of HIT, suggesting an interplay of genetic and environmental factors.

Abstract
Diarrhea is a side effect of a 5-fluorouracil (5-FU) anti-cancer drug-induced intestinal mucosal disorder, which sometimes becomes more severe. Blood diamine oxidase (DAO; EC1. 4. 3. 6) activity is reported to be significantly correlated with activity in the small intestinal mucosal tissue, and to be a reliable indicator of small intestinal mucosal integrity and maturity. Here, we investigated whether blood DAO activity can be a biomarker for the gastrointestinal (GI) mucosal disorder caused by 5-FU anti-cancer drugs, both in rats and humans. From results of the rat study, the degree of jejunal mucosal disorder caused by the 5-FU anti-cancer drug was well correlated with a decrease in blood DAO activity. Clinically, 12 out of 28 patients (43%) administered 5-FU anti-cancer drug suffered from diarrhea. The plasma DAO activity within one week of the onset of diarrhea significantly decreased compared with that before the administration. Furthermore, before drug administration, plasma DAO activity in patients suffering from diarrhea was higher than those in patients without diarrhea. Although DAO activity differs by the individual, it is a useful biomarker for estimating the degree of intestinal mucosal disorder, and possibly for estimating manifestations of diarrhea induced by 5-FU anti-cancer drug administration.

Abstract
OBJECTIVE Vascular adhesion protein-1 (VAP-1) participates in inflammation and catalyzes the breakdown of amines to produce aldehyde, hydrogen peroxide, and ammonia. Serum VAP-1 correlates positively with both acute hyperglycemia and diabetes. We conducted a cohort study to evaluate whether serum VAP-1 predicts 10-year survival in type 2 diabetic patients. RESEARCH DESIGN AND METHODS Between July 1996 and June 2003, we enrolled 661 type 2 diabetic subjects at National Taiwan University Hospital. Serum VAP-1 in the samples obtained at enrollment was measured by time-resolved immunofluorometric assay. The vital status of all subjects was ascertained by linking their data with computerized death certificates in Taiwan. RESULTS The medium follow-up period was 10.4 years. Subjects with serum VAP-1 in the highest tertile had a hazard ratio (HR) of 2.19 (95% CI 1.17-4.11) for all-cause mortality adjusted for age, sex, smoking, history of cardiovascular disease, obesity, hypertension, hemoglobin A(1c), diabetes duration, total cholesterol, use of statins, abnormal ankle-brachial index, estimated glomerular filtration rate (eGFR), and proteinuria. The adjusted HRs for logarithmically transformed serum VAP-1 were 5.83 (95% CI 1.17-28.97) for cardiovascular mortality, 6.32 (95% CI 1.25-32.00) for mortality from cardiovascular and diabetic causes, and 17.24 (95% CI 4.57-65.07) for cancer mortality. There were four variables, including age, serum VAP-1, proteinuria, and eGFR, which could enhance mortality prediction significantly. CONCLUSIONS Serum VAP-1 can predict 10-year all-cause mortality, cardiovascular mortality, and cancer mortality independently in type 2 diabetic subjects. Serum VAP-1 is a novel biomarker that improves risk prediction over and above established risk factors.

Abstract
AIMS/HYPOTHESIS Recent studies have provided evidence that intrauterine exposure to maternal diabetes has lifelong effects on adult offspring, including increased risks of obesity, type 2 diabetes and cardiovascular disease. The aim of this study was to assess the relationship between exposure to maternal diabetes in utero and cardiovascular risk factors in healthy children and to investigate whether these associations are independent of maternal prepregnancy BMI and offspring attained BMI. METHODS Data were from a retrospective cohort of children aged 6-13 years born during 1994-2002. Multiple linear regression was used to examine the associations between exposure and cardiovascular risk factors with adjustment for demographic factors and pubertal stage and additionally for maternal prepregnancy BMI and offspring attained BMI. RESULTS Ninety-nine offspring of diabetic pregnancies had significantly increased E-selectin, vascular adhesion molecule 1 (VCAM1), leptin, waist circumference, BMI and systolic blood pressure and decreased adiponectin levels compared with 422 offspring of non-diabetic pregnancies after adjustment for age, sex and race/ethnicity (p < 0.05 for each risk factor). Additional adjustment for maternal prepregnancy BMI substantially attenuated group differences in the risk factors except for E-selectin, VCAM1 and waist circumference, which remained significantly higher in exposed children. CONCLUSIONS/INTERPRETATION Compared with unexposed children, healthy offspring exposed to maternal diabetes in utero have a worse cardiovascular risk profile. In particular, offspring have substantially increased levels of circulating cellular adhesion molecules, which are biomarkers of adverse endothelium perturbation and may be related to the earliest preclinical stages of atherosclerosis and diabetes.

Abstract
Oxidative stress is a pathogenetic factor of ischemic stroke. Enhancement in the activity of one of xenobiotic transformation enzymes and biogenic amines (serum semicarbazide-sensitive amine oxidase (SSAO)) leads to the higher production of secondary toxins stimulating oxidative stress. We studied 38 patients (mean age 69,5 +/- 7,2 years) in the early restoration period of ischemic stroke. A control group included 17 age- and sex-matched healthy people. Severity of neurological and functional deficits was assessed with the NIHSS and the Barthel index, respectively. A number of biochemical parameters: serum SSAO activity, concentration of middle-sized molecules (MSM) and malonic dialdehyde (MDA) were measured. The higher concentration of MSM (0,80 +/- 0,22 and 0,5 +/- 0,1 g/l) and MDA (4,5 +/- 1,25 and 3,66 +/- 0,15 mmol/ml), respectively, was found in patients compared to the controls (p < 0,001). The correlative increase in MSM and MDA suggest the formation of chronic oxidative stress in the 4-5 months of disease. The changes in SSAO activity in patients with ischemic stroke that differed from controls were seen in 84% of cases while the increase in SSAO activity was found in 31% of patients. The pathogenetic link between the increase in SSAO activity and severity of neurological deficit was shown. This increase might be one of the pathogenetic links in the disturbance of neuroplasticity.

Abstract
OBJECTIVES The aim of this study was to investigate the effect of continuous blood purification (CBP) on early gut mucosal dysfunction in patients with severe acute pancreatitis (SAP). METHODS Patients with SAP were randomized to receive 24 hours of continuous veno-venous hemofiltration (CVVH; n = 33) or no CVVH (n = 30). Blood samples were taken from the patients at 0, 6, 12, and 24 hours during CVVH therapy. Serum diamine oxidase (DAO) and endotoxin, epithelial permeability, transepithelial electrical resistance (TER) and F-actin rearrangement of the epithelial monolayer were used as the markers for the assessment of gut barrier function and the effect of CBP therapy in patients with SAP. RESULTS Patients with SAP had increased levels of serum DAO, endotoxin, and epithelial permeability when compared with normal controls, and the increase was more pronounced in patients with organ dysfunction (p<0.01). F-actin rearrangement, loose cell-cell junction, and iNOS mRNA upregulation were found in all patients. After CBP treatment, Acute Physiology and Chronic Health Evaluation II score and SOFA score improved significantly; levels of serum DAO, endotoxin, and epithelial permeability decreased(p<0.05). CBP also significantly attenuated reorganization of actin and downregulated iNOS mRNA expression and NO production (p<0.05). CONCLUSIONS CBP can not only improve the general conditions but also effectively improve gut barrier dysfunction. The beneficial effect of CBP on gut barrier dysfunction is associated with the improvement of cytoskeletal instability, by downregulating iNOS through the removal of excess proinflammatory factors.

Abstract
Marginal copper deficiency has been proposed to occur frequently, but the benefits of correction remain largely uncharacterized. Two benefits could be reduced oxidant stress and better crosslinking of collagen in bone. Copper intake was increased in 8 female university students by supplementation with copper glycinate (2 mg copper/day) for 8 weeks. Supplementation improved copper status based on serum activity of two copper enzymes, ceruloplasmin and diamine oxidase (9% and 75% mean increase, respectively). No effect was seen for erythrocyte copper-zinc superoxide dismutase. Supplementation produced a 39% mean decrease in plasma for F(2alpha)-isoprostanes (a marker of oxidant stress), and gave a 62% increase in the urine ratio of collagen crosslinks to a measure of total collagen. None of the supplementation effects were duplicated for 8 women given placebo. In conclusion, this pilot study found that in young adult women, increased copper intake can alter biochemical parameters relevant to copper function.

Abstract
This study aimed to evaluate the semicarbazide-sensitive amine oxidase (SSAO) activity in human arterial tissues and in serum of patients with type 2 diabetes. The SSAO activity, with (14)C-benzylamine as substrate, was measured in homogenates of human inferior mesenteric arteries obtained at surgery, from 10 patients with type 2 diabetes and 16 non-diabetic patients and in the serum of 39 patients with type 2 diabetes and 40 non-diabetic control patients. The SSAO activity in the homogenates of vascular tissue was significantly lower in the diabetics than in the non-diabetics (P = 0.001). The SSAO activity in the serum of patients with type 2 diabetes was higher when compared with control group (P = 0.0001). In conclusion, the SSAO activity increased in the serum and decreased in the arterial tissue. These findings suggest damage in the vascular tissue and support the hypothesis that serum SSAO may be a useful biochemical marker for diabetes.

Abstract
Ceruloplasmin (Cp) is a multicopper oxidase and the most abundant copper binding protein in vertebrate plasma. Loss of function mutations in humans or experimental deletion in mice result in iron overload consistent with a putative ferroxidase function. Prior work suggested plasma may contain multiple ferroxidases. Studies were conducted in Holtzman rats (Rattusnorvegicus), albino mice (Mus musculus), Cp-/- mice, and adult humans (Homo sapiens) to investigate the copper-iron interaction. Dietary copper-deficient (CuD) rats and mice were produced using a modified AIN-76A diet. Results confirmed that o-dianisidine is a better substrate than paraphenylene diamine (PPD) for assessing diamine oxidase activity of Cp. Plasma from CuD rat dams and pups, and CuD and Cp-/- mice contained no detectable Cp diamine oxidase activity. Importantly, no ferroxidase activity was detectable for CuD rats, mice, or Cp-/- mice compared to robust activity for copper-adequate (CuA) rodent controls using western membrane assay. Immunoblot protocols detected major reductions (60-90%) in Cp protein in plasma of CuD rodents but no alteration in liver mRNA levels by qRT-PCR. Data are consistent with apo-Cp being less stable than holo-Cp. Further research is needed to explain normal plasma iron in CuD mice. Reduction in Cp is a sensitive biomarker for copper deficiency.

Abstract
BACKGROUND Semicarbazide-sensitive amine oxidase (SSAO) is found in various mammalian tissues, particularly in vascular smooth muscle cells, but also in plasma. It has been suggested that it plays an important role in vascular endothelial damage and in progression of atherosclerosis through conversion of endogenous amines into cytotoxic aldehydes, ammonia and hydrogen peroxide. In patients with diabetes mellitus and chronic heart failure, plasma activity appears to rise in parallel with disease severity. METHODS AND RESULTS Plasma SSAO and monoamine oxidase (MAO) activity was measured in 39 patients with hypertensive heart disease and left ventricular systolic dysfunction, in NYHA heart failure class II-IV, and compared to values in 89 controls. SSAO was found to be elevated in patients compared to controls (2.781 +/- 1.599 vs. 1.627 +/- 0.751 micromol/l/h; p = 0.000). Plasma MAO was also significantly increased in the patient group (3.837 +/- 1.899 vs. 3.077 +/- 1.559 (micromol/l/h; p = 0.018). No significant differences were seen between different NYHA classes, but class IV patients presented the highest SSAO activity. SSAO and MAO activity showed a trend for a positive correlation (R = 0.265; p = 0.092). CONCLUSION The finding of elevated plasma SSAO and MAO activity in congestive heart failure supports the hypothesis that amine oxidases may be involved in the pathogenesis of vascular endothelial damage.

Abstract
OBJECTIVE To study the change of intestinal mucosa barrier in chronic severe hepatitis B patients and clinical intervention. METHOD (1) 30 normal healthy controls and 60 chronic severe hepatitis B patients were enrolled in this study. The change of intestinal permeability was determined by urine lactulose/ mannitol ratio (L/M), and the serum diamine oxidase (DAO) was measured. (2) 60 chronic severe hepatitis B patients were randomly divided into two groups: the control group and the treated group, each group has 30 cases. Patients in the control group received standard treatment for 2 weeks, however, in addition to standard treatment, patients in the treated group also received glutamine 10g tid. Endotoxin (ET), DAO and L/M were compared between the two group. RESULTS (1) Compared to healthy controls, the level of L/M and DAO was significantly increased in chronic severe hepatitis B patients (t = 2.762, P less than 0.01 or t = 6.326, P less than 0.01). (2) Compared to the control group, ET, DAO and L/M were significantly lower 2 weeks after treatment (F = 11.662, P less than 0.01; F = 12.699, P less than 0.01; F = 19.981, P less than 0.01). CONCLUSION (1) There is an early intestinal mucosa barrier damage in chronic severe hepatitis B patients. (2) Compared to standard treatment, adding glutamine can reverse intestinal mucosa barrier damage.
